ZnO-WO,触媒上におけるエタノールの分解反応

抄録

The decmposition of ethanol was carried out on the ZnO-W0₃ catalysts. The phase structures of the active catalysts were investigated by powder X-ray diffraction analysis. Both the diffraction intensity of WO, and the activity for dehydration of ethanol decreased with the increase of the content of ZnO in the ZnO-W03 catalysts. The maximum dehydrogenation activity was observed on the catalysts containing 50-60mol% of ZnO, giving the maximum diffraction intensity of ZnWO₄. In spite of the existence of ZnWO₄, the catalysts containing less than 50mol% of ZnO were almost inactive for the dehydrogenation (Fig.1). The role of ZnWO₄ catalyzing the dehydrogenation of ethanol was briefly discussed.
